Visual Editor will be our quick preview tool throughout this series

Visual Editor


Adjusting Global Options in the RStudio IDE

😄 Pro tip: cmd+, to access global options


Rearrange panels


Change theme


Show chunk output in console


Default R version & don’t save workspace data


Set repo for RStudio Public Package Manager

😄 Pro tip: If you are on a Linux server, see what operating system you are on by running this in your console: 


system("lsb_release -a")


Then go to RStudio Public Package Manager


Allow scroll past end of doc & rainbow parentheses


Command Palette is amazing!

😄 shift+cmd+p then do anything

Use shift+cmd+p to access the command palette and:

  • Toggle Memory Usage Display in Environment Pane
  • Syntax highlighting in console output
  • Knit Current Document
  • Highlight Selected Line


Adjust the code chunk options at the top of this file to hide code and re-knit


Expand the outline

😄 Pro tip: Navigate your document with the outline 

😄 also ctl+shift+o

 

 


Outline is also down here



Code folding

Go back up to the line “set repo for RStudio Public Package Manager”
😄 Click the little triangle next to the line number



Command History in the console

😄 Pro tip: in the console type a couple of letters then cmd+up for visual of matches

 


Open File in New Column

😄 Pro tip: open file in new column is great for Shiny apps when you have ui, sever, and css files



Comment and not

😄 Pro tip: highlight multiple lines of code, shift+ctl+c to comment all


Move line

😄 Pro tip: alt+up or alt+down to move lines


Multi-line

😄 Pro tip: ctl+alt+down or ctl+alt+up to have multi-line cursor
You try: add commas after starts_with() and mean

df %>% 
  summarise(
    across(
      starts_with("culmen")
      mean
      na.rm = TRUE
      )
    )


Which parentheses?

😄 Pro tip: double click one of the parentheses to highlight what it contains

div(
  class = "outer",
  div(
    class = "container",
    div(
      class = "data",
        df %>% 
          filter(
            str_detect(Species, "Chin"),
            Sex == "MALE",
            Island == "Dream"
          ) %>% 
          summarise(
            across(
              starts_with("culmen"),
              mean,
              na.rm = TRUE
            )
          )
    )
  )
)


Execute long-running code in jobs

😄 Pro tip: execute code or scripts as jobs in separate R sessions so you can keep working in your IDE

Jobs

git in the IDE (a very short intro)

😄 Pro tip: ctl+alt+m to open the commit window
😄 Pro tip: can stage or discard chunks, even lines
😄 Pro tip: select first file then cmd+a to highlight all, then check one to check all

Git discard
